Java performance tuning
Java performance tuning is a function of many things, such as code, networks, hardware (client configuration, memory, CPU speed, storage capacity, etc.) and databases. It is almost impossible to predict exactly where a performance tuning failure might occur. Performance tuning tools allow you to take applications to their point of failure by using virtual users. Java performance tuning must be precise to simulate concurrent load at exactly the same instant. With manual performance tuning, human reaction times simply can't achieve and maintain the same level of concurrency as seen with automated tools. Find the latest information and tuning best practices in this topic section.
